Application led Heeeniber 7, l. Serial No. 285,70?.

a citizen of the United States, and a resident of the city of New York, in the county of New York 'and State of New York, have invented a new and useful .lmproife'inent in Car-Roots, of which the following is a This invention relates to outside metal car roofs of the type shown. and described in the C. C. Murphy Patent No. 1,133,493, dated March. 30, 1915, wherein the roeiC sheets are pivotally mounted on, the sulr structure on opposite sides of the ridge, and it relates 4particularly to the intermediate, running board saddle or anchor' saddle used in this type of roof. vIn the above root, d iil'loulty. is sometimes experienced with the IWooden anchor saddles, whose purpose is to hold the roofsheets in engagement with the pivots, and also hold thereof sheets inposition on the substructure. These wooden saddles are provided with holes through which the bolts for securing' the saddles to the `substructure pass. In actual practice thesaddle is liable to rot out and wear around the bolt hole; and the saddle is also liable toshrink and warp and the portion of the saddle which rests on the sheet liable to split off. In such event, the sheet is liable to ride up on its pivot and thus become dislocated. This alsoA allows cinders and grit to i accumulate, and the rubbing action is liable to wear the galvanizing ofl the sheets and thus cause the sheets to rust; while' the yoinders which contain sulfur will eiiect rapid corrosion. This action isv4 aggravated by the moisture retained in the wood, which causes the wood to swell and clamp the sheets too tightly; whereas the engagement of the saddle 4with the sheet-is liable te be insuiirient when the. wood is thormighlj,T dry.

The principal object of the. present 'invention isl to produce a sheet anchor which will overcome the disadvantages hereinbefore mentioned. Anotherl object is to curely fasten the sheet anchor te the ear so lthatit will not become loose during the service of the car. ther objects are: 'to prevent leaks around the securing bolt; te cheapeu the cost of manufacture and application of the, anchor saddle; to reduce the -size thereof; and to improye the apwarauce 'of the roof.

The invention consismin the improved niet al sheet anchor lor binding ti portion of the roof on the line 3 sheets on their pivots, :ind in the combinations and arrangements of .parts herein-v after described and claimed.

in the accolnpanyingdrawing, which forms part of this specification, and wherein like symbols reifer to like parts wherever they occur,

Figure l is a plan i'iew of a car root1 embodying my invention, parts of the root being shown broken away to more clearly illustrate the invention;

Fig. is an enlarged plan View of the ridge portion of the root' in the region of 'the sheet anchor:

Fig. 3 is a cross section through the ridge 3 in Fig. 2;

Fig. 4: is a cross section through the eaves portion oi the car on the' line 4 #t in Fig'. l; and

Fig. 5 is a cross section through one of the transverse seams on the line 5 5 in Fig. l.

The roof is illustrated in the accompanying drawing and comprises side sheathing (i, roei' sheathing 7, supported at theeaves by side plates S, and at the ridge hy means of a ridge pole 9, all of well known construction. The root sheets l() are arranged transversely of the car in pairs on opposite sides ot the ridge andare provided at their 'side and ridge .margins with inwardly hooked upstanding Hannes 1l and 12. At their eaves/ends, the sheets are doubled under, as at 13, parallel with the body portion ot the rooic sheets but spaced far enough below said body portion to accommodate the rebent portion 14 ot a continuous eaves flashing` strip 15. This flashingr strip lies in a rabbet formed iu the eaves portion of the root sheathing and is turned down over the side ot the car and secured to the side sheathing by nails or other suitable securing means At the side margins, each pair of root' z-"ets spaced .trom the adjacent pairs; and, in. the spare thus Jformed. are arranged mullious or battons 1G. These n ions 1G extend transversely "from eaves o @aigre on opposite sides ol1 the romn and are ol less width than the spaces between the side margins of the rool" sheets. Transverse seam caps 17. of inverted channel shaped section. straddle the inullions lo and the adjacent side margins oic the root' sheets. and the lower edges oic the side walls of said caps have inwardly and upwardly inclined ilanges le' which interlock with the seam root' sheet. flanges 11 at the side'margins of the root sheets. The transverse seam caps extend Jrom eaves to ridge, and their` eaves ends are held down by bending their ends under the ends of the iniillions or in any other desired manner.

The sheets are spaced apart at the ridge, and a ridge seain cap 19 similar in cross section to the transverse seam caps 17 straddles the adjacent lridge margins ot' each pair of sheets. The lower edges of the Side walls of the i'idge seani cap have flanges 20 which interlock with the hooked flanges 12 at the ridge margins of thereof sheets in a manner similar to the transverse seam construction. The ridge `ends ot the transverse seam caps and. the :uljacent ends of the ridge seam caps are covered b v the usual fourway corner caps 21. The corner caps are secured to the substructure iii a usual inanner b v bolts which also secure the running board saddle 22, in position. Running boards .3 are secured to the ruiming board saddles which rest on the transverse seam caps and are supported by the iniillions, thus permitting` movement of the root` sheets luider the seam covers.

Each sheet ot' a pair ot oppositely disposed roo'f sheets is pivoted to the roof substructure at the middle portion ot its ridge end by a sheet metal saddle plate 2st. The saddle plates straddle the ridge portion of the. car and are provided near their end poi'- tions with inverted cup shaped pivot bosses` Q5 having inclined side 'alls which tit into similar or counter-part upstanding bosses 2o which are centrally locatedl in the sheets near their ridge. ends. llhe oppositely disposed bosses 26 ot' each pair ot root sheets are held in position on the pivot bosses 25 ot the saddle plate Q4 by means ot a sheet anchor saddle 27 located at'- the ridge on a transverseline between the oppositely disposed bosses Qt' ot' each pair of root sheets. This anchor saddle, which is preferably made in the form of a malleable casting comprises an inverted channel shaped portion QS having lateral portions 2t) extending outwardly from the lower edge ot' each side wall of the channel shaped portion Q8. The

channel shaped portion ot' the anchor saddle straddles the ridge seam cap and the anchor saddle is secured to the substructure by means of a .vertical bolt 30. which passes through a bossed up hole 31 in the ridge seam cover.

The ends ol" thel laterally extending' portion 29 lot the anchor saddle are provided with flanges 32 which are curved or forked to tit the. circular bosses ot the root sheets 2G and are also inclined upwardly and outwardly to correspond to the inclination o't tho'si-de walls otl the bosses. 'lhe vertical bolt' 30, which secures the anchor saddle to the substructure,v extends upward through the ridge pole 9 and root sheathing 7, and passes through a hote in the saddle plates 24, thus holding this meniber in position. The bolt then passes through the bossed up hole 31 in the ridge seam cover and is threaded into a hole in a boss 33 which pro-l jects upwardly troni the channel shaped portion 2S ot tl ilanchor saddle. The bolt is prevented Jfrom working loose from the anchor saddle by means ot a lock nut 3ft which is screwed down tight on the boss 33 ot' the anchor member and also prevents water following theI bolt and rcachii'ig the interior o'li the cai'. The top ot the anchor saddle provided with a stitlcniiig rib $55 which extends from the medial boss 33 to thel inclined circular tlanges 32 at the ends ot the anchor saddle. The threaded hole in the boss of the anchor saddle, into which the upper end ot the bolt 3() is threaded, is counter-sunk on its under side to receive the bossed up portion 3h of the ridge sean! cover. 'lhis prevents water, which may get between the underside ot the bottom ot the channel sha )ed portion '2S ot' the ancho and the top ot' t e ridge seam cap` troni entering the ear.

B v the arrangement described. a water tight joint between the anchor saddle and the seam caps is obtained` and the tendency ot' the anchor saddle bolts to become loose is overcome.
